Becky's Performance Pizza is a small restaurant in Detroit that sells gluten-free pizzas. Becky's very tiny kitchen has barely enough room for the four ovens in which her workers bake the pizzas. Becky signed a lease obligating her to pay the rent for the four ovens for the next year. Because of this, and because Becky's kitchen cannot fit more than four ovens, Becky cannot change the number of ovens she uses in her production of pizzas in the short run.

However, Becky's decision regarding how many workers to use can vary from week to week because her workers tend to be students. Each Monday, Becky lets them know how many workers she needs for each day of the week. In the short run, these workers arevariable inputs, and the ovens arefixed inputs.

Becky's daily production schedule is presented in the following table.

Suppose that labor is Becky's only variable cost and that she has a fixed cost of $30 per day and pays each of her workers $30 per day.

Use the orange points (square symbol) to plot Becky's total cost curve on the following graph using the quantities from the preceding table.
